Why did Donald Trump, a real estate mogul and reality TV star with no political experience, decide to run for president?

We have no shortage of theories. Some say Trump wanted free publicity to boost his sagging personal brand. Others assert it was all a stunt to launch a new cable TV channel. Still others insist Trump jumped in to shake things up and have a little fun, never expecting to actually win the Republican nomination.

Now Trump’s son Eric has put forth a new theory: His father was upset because the White House Christmas tree was renamed a “holiday tree.”

The biblical book of Acts tells a story about the Apostle Paul, known as the greatest church planter in the history of Christianity, walking through the streets of Athens and encountering people from diverse faiths and belief systems.

If you’ve read any of Paul’s letters, you know he was an intense and passionate man, dedicated to evangelizing as many people as he could. Yet, his approach to the Athenians, a people living in a pluralistic society, was not one where he set out to negate or repudiate the value of other religions being practiced.

Editor’s Note: Today Americans United and American Atheists filed a lawsuit challenging the Pennsylvania House of Representatives’ invocation policy, which excludes non-theistic voices. Three of the plaintiffs in the case, Brian Fields, Deana Weaver and Scott Rhoades, recently took part in a Q&A and explained what motivated them to get involved in this litigation.

The Religious Freedom Restoration Act (RFRA) of 1993 was intended to protect the fundamental American value of religious freedom.

In the more than two decades since RFRA’s passage, however, the law has too frequently been misused and misinterpreted as a sword to harm others, rather than as a shield to protect religious liberty. In particular, some ne’er-do-wells have tried to manipulate RFRA into a tool that allows them ignore non-discrimination laws.

A Florida court just threw out an appeal brought by Americans United and its allies challenging a school-voucher-like program that provides taxpayer support for religious organizations. As disappointing as that outcome is, it’s doubly frustrating to see a second Sunshine State court fail to even consider the merits of the case.

Republican presidential nominee Donald J. Trump has vowed to repeal a federal law that bars houses of worship (and other tax-exempt non-profits) from endorsing or opposing candidates for public office.
